FIRSTINFO A1135QUS Patented 10 Liter 22 Pcs Taiwan-ATF Filler Adapters | Pneumatic Transmission Fluid Dispenser Pump | Hanging Hook | 360° Z-Swivel Air Inlet | Spring Structure Hose

Once I used this tool I wondered why I didn't buy it years ago, because it's such a pleasure to use. If you have any need to remove or pump in ATF or gear oil, this pumping tank will do the job. I have no idea how it works, but by flipping a lever and turning a knob, the tank either sucks or pumps with the squeeze of a handle; pretty cool.Yes, the top can be difficult to remove the first time, but a couple of long screwdrivers (through the tank handles and through the lid) will give you enough leverage that removal is no big deal.When I first used this pumping tank I thought it had an air leak, but evidently that's normal; it uses a lot of air while actually in use.Changing from pumping out to pumping in is a bit of an ordeal, because you want all of the old oil out of the lines and the tank before filling the tank with fresh oil. I hang the dispenser handle up on the garage wall for a while to let the line drain (dispenser handle has to be squeezed while you do this, to let air into the hose). While the hose is draining I pour the old oil out of the tank, then leave it upside down while I go get a cup of coffee, to let both the tank and hose fully drain.I was initially hesitant to buy this tool, since it's not exactly inexpensive. But it seems well designed, well made, comes with lots of specialty fittings, and works well. For me, it paid for itself the first time I used it. Two thumbs up.

I tried another ATF dispenser and found this one to be much better built and working well. The size is also appropriate for the transmission work on my 4runner. The adapter fits my 4runner better than the other dispensor i tried due to flexible body, and the trigger is also easier to use for quick changes since it is press type.I could open the lid - applied petroleum jelly to the lid grooves so that it remains easy to open it. I have not used its ability to suction, but guessing from its build that it should be atleast same (or likely better) to the other ATF dispensors as per most reports arent too strong on suction, and suction work slowly.I got one without swivel and a spring - the unit worked fine and hence I am happy with it.

I purchased this tool to do a drain and fill on my Porsche Panamera PDK transmission which would save me a boatload of money. It came with a good variety of adapters and hoses to get the job done. The adapters are made of metal which is a real plus. It seems to move oils and other liquids in or out at a decent rate. Not too fast or too slow. It also seems to be well built with good quality materials. One issue is the cap is purposely and unnecessarily screwed on and torqued down so tight that it can't be removed by hand. The problem is if you extract dirty oil with it, you need to clean the inside and dry it out before you go back with clean fresh oil. That's very hard to do if you can't even take the lid off. Because its much easier to clean and dry it out if you can take the cap off. I had to use a bench clamp to get the cap off. The thing works perfectly fine with the lid hand tight. I don't understand why in the world they make it impossible to twist the cap off by hand. Next issue is, I tested it with air pressure when it first arrived. It would not hold any air pressure for more than a few seconds. I thought it was defective. But after I tried it in the field it worked fine. I guess its really not supposed to hold pressure. It seems to just let pressure build and constantly seep out as long as the black handle trigger is locked. This means your air compressor will constantly be blowing air through it trying to keep the pressure up in the bottle. The next issue is the claim that it can hold 10 liters. I believe it's more like 9.5 liters. It's got a line on the bottle for every liter. I tested it by pouring in 10 one liter bottles of oil in it at room temperature and it could only hold 9.5 liters filled it all the way to the rim. I guess they just call it 10 liters by rounding it up to 10. I guess this is fine if you only need a 9.5 liter oil dispenser. That's the only reason I gave it 4 stars instead of 5. I do wish they made it out of a clear acrylic or clear plastic but overall I'm very satisfied with it. I don't know the longevity or the reliability of it because I've only used it once and I probably won't use it no more than 1 or 2 times a year. The warranty will probably be long gone by the time I use it again but as of today I would highly recommend it as long as you have no problem with the issues I've mentioned.

If you're filling a differential or a transfer case with the old style pumps that go on top of the court. Those are fine, but if you doing a transmission that takes 9 liters, that would take forever. This pump quickly pumped 9 l in has a great assortment of tips.And the hangar is a nice feature so you can hang it next to where you're working. Highly recommend

Good product

It seemed capable, but a little bit frustrating sometimes; I found that instead of simply allowing the tank to pressurize to 43PSI, the unit consumes air just as fast on Dispense mode as it does on Extract mode- which is a good amount of consumption. It similarly doesn't allow vacuum pressure to build as an automatic/manual type would, so it's ALWAYS using air- you can't pressurize the bottle, and just let it extract or dispense until the pressure is gone.I've only used it for ATF+4, which is fairly flowable, but seemed to be a bit slow... maybe it's me, but it felt like it took almost 8 minutes to pull out 6L.Anyway, it does seem fairly well built- the plastic castings seem sturdy, the connections don't leak, and it does extract and dispense the fluids I bought it for- I wish it had included a brake bleeder connector, because that's a pretty common use for these, and for the price it would be a tiny bit of loss for the manufacturer- especially because they make the silicon casting for the bleeder connection already.I'd get another, but only if absolutely necessary that I have something to perform this function.

Excellent transfer pump for transmission fluid changes.. used it on my 2021 GMC Sierra 1500 LM2.. Dispensed fluid into the transmission less than minute.
